Taladnudbaan
Designing the full-scale property marketplace for the Real Estate Information Center of Thailand, covering 40+ modules across consumer discovery and platform administration.
A government property marketplace built on a customized platform engine.
The Real Estate Information Center (REIC) is a state agency responsible for property market data across Thailand. Taladnudbaan was their consumer-facing marketplace, connecting buyers with a national property database covering residential listings, price history, mortgage tools, and market intelligence.
The platform was built on top of an existing marketplace engine and expanded significantly through customization. My role was to interpret a detailed TOR across 40+ feature requirements, design each surface, flag ambiguous requirements back to stakeholders, and deliver UI for both the consumer platform and the administration system.
The work spanned two distinct audiences with different needs: buyers and sellers navigating property decisions, and platform operators managing listings, content, users, and system configuration on the backend.
What was designed.
Consumer Platform
Administration Platform
Selected surfaces from the platform.
Homepage with property search, sponsor bank partners, featured listings, news and articles, and newsletter signup, serving both first-time buyers and returning users.
Search results in three layouts: list, grid, and map, letting buyers switch between density and spatial context depending on how they browse.
Side-by-side comparison of up to three listings across price, size, location, and attributes, reducing friction during the shortlisting process.
News listing and article detail pages, part of the content hub covering property market updates, event calendar, and editorial articles for buyers and sellers.
Property detail page consolidating hero gallery with 360° view, listing specs, interactive map with nearby schools, hospitals, malls and transit, price history, inline mortgage calculator, bank partner rates, and similar listings.
Mobile app covering search, property detail with photo gallery, news feed, and recommended listings, extending the full platform experience to iOS and Android.
Challenges I worked through.
Translating TOR Requirements into Designed Surfaces
The project was defined by a detailed TOR with numbered requirements across search, map, member system, calculators, and content. Each requirement needed to be interpreted, questioned where ambiguous, flagged back to stakeholders where incomplete, and translated into a UI decision. Not every item was straightforward. Some needed clarification on scope, some conflicted with platform constraints, and some required design judgement on how to present complex data without overwhelming the user.
Calculators That Answer Real Buyer Questions
Two calculators addressed the financial questions buyers face before committing to a property. The mortgage eligibility calculator takes income, age, loan term, and interest rate to output borrowing power and estimated monthly installment. The transfer fee calculator breaks down the full cost of ownership transfer: stamp duty, withholding tax, and mortgage registration fee. Both needed to handle Thai-specific financial rules and present results in a way that was easy to act on.
Designing for Two Audiences on One Platform
The consumer side needed to feel approachable and decision-focused. The admin side needed to give operators full control over listings, users, content, banners, and system configuration, often used by non-technical staff. Both surfaces shared the same underlying data but served opposite interaction patterns: one optimized for discovery and exploration, the other for management and oversight.
What I worked on.
Requirement Interpretation
Worked directly from a detailed TOR, interpreting each requirement, flagging ambiguities back to stakeholders, and making design decisions where specifications were incomplete.
Consumer Platform UI
Designed all buyer-facing surfaces including homepage, search, map browse, property detail, comparison, calculators, and member account flows.
Admin Platform UI
Designed the admin dashboard and management interfaces covering listings, users, content, banners, sponsors, newsletter, and system configuration.
Decision Support Tools
Designed the mortgage calculator, property comparison tool, saved search, and favorites to support buyers from discovery through to decision.
Multi-Role System
Designed role-based access and permission structures for super admin, content editors, and seller accounts operating within the same backend.
Platform Customization
Adapted and extended an existing marketplace engine through UI customization, feature design, and requirement-driven additions specific to the Thai real estate market.
